MACHINE FOR OILING 0B PAEIINTING EXPOSED RAILROAD STRUCTURES.

Application filed February 23, 1924. Serial No. 684,799.

My invention relates, in general, to railroad appliances, and, in particular, to a machine for oiling or painting rail-track fastenings, switches and other railroad structures.

The object of my invention is to" provide a simple and effective machine for this purpose, with resulting economy in the matter of protecting and prolonging the life of exposed structures on railroads.

To this end my invention consists in the novel machine which I shall hereinafter fully describe by reference to the accompanying drawings, it being understood that various changes may be made in the construction, both. in .detail and arrangement,

of the machine and its several parts withoutdeparting from the spirit of the invention as defined by the claims hereunto appended.

In the drawings Fig. 1 is a side elevation of my machine. Fig.2 is a detail of the concentric nested members 57 which operate the several clutches of the driving shaft 6.

Fig. 3 is a longitudinal section, enlarged, of-the preheater.

Fig. 4 is a plan view of my machine.

Fig. 5 is a plan view, enlarged, of the rail I protecting slide-shoe and associated spraying members.

Fig. 6 is a side view of the same.

Fig. 7 is a section on the line 7-7 of Fig. 6.

Referring to Figs. 1 and 4 the numeral 1 is a car with wheels 2 adapted to run on the track rails 3 of a railroad bed 4. The car is driven by a suitable internal combustion engine 5' having a drive.- shaft 6.

Upon the car is mounted the reservoir 7 for containing the oiling or painting liquidmedium. Y

The car also carries th preheater 8 for rendering the lnfiid medlum sufliciently lim idior use. e preheater comprises a she 1 through which pass tubes 8 as seen in F1 3. These tubes communicate at one and t rough a connection 9 with the interior of the reservoir 7, and at the other end they communicate with the suction side cit a pressure pump 1Q Fig. 4, through a connection 11 fitted with a controlling valve 11. The liquid-medium is thus; drawn from the reservoir 7, through the tubes-8 of the preheater 8 into the pump 11). The interior of the shell of the preheater, around the tubes, is in communicative relation with the exhaust 12 of the engine 5, so that the exhaust gases in passing through said shell to their outlet at 13, heat the liquid-medium in the tubes 8. A cut-out lat-is provided in the exhaust 12, Fig. 1.

Carried upon thecar is a pressure-chamber 15, within which is a hollow filter 16, Fig. 1. The discharge side of the pump 10 connects through a pipe 17 Fig. 4, with the pressure chamber 15; whilethe filter 16 communicates with a pipe line 18, Fig. 1, controlled by a valve 18'; said line-leadin to the several devices, hereinafter descri ed, for applying the liquid medium to the parts to be protected. Thus said pump delivers the liquid medium to the pressure chamber 15, and said medium passes through the filter 16 into the pipe line 18.

The pressure chamber 15 communicates directly with the reservoir 7 through a bypass 19 fitted with a valve 20, and a safety re of valve 21, Fig. 1 to automatically maintain a predetermined pressure in said chamber when the pump is in motion, even though all other openings from said chamber be closed.

The bottom of the pressure chamber is provided with a drain 22, and the'top chamber of the filter is fitted with a pressure gauge 23. v

Coupled by means of a union at 24 Fig. 4,

to the pipe line 18, near its rear end 1s a pipe 25 which extends across the car 1 at its rear. The pipe 25 has va1ves25 and is fitted with a coupling 26 at each end, for a flexible hose 27, carrymg a nozzle 28 with a spraying ti 29. of any suitable construction. Beyon the union of the cross pipe 25 with the pipe line '18, said pipe line 1s fitted with a controlling valve 30, Fig. 4; and beyond said valve, the pipe line 18 is coupled to a header pipe 3 1 which is mounted across the rear of the car 1','said header pipe being rotatable upon its axis- Coupled to each end of the cross header pipe-31. is a'rear-- raying members and carried by them are ihe slide shoes 35,

From form, adapting them, to slide and normally the sprocket extends a chain 51 to a rest the1r weight upon the heads of the sprocket 52 on the end of a shaft 53 mounted .track rails 3 and freely envelop the sides transversely on the front of the car. The
